Abstract
Much progress in optical flow research has been driven by benchmark datasets. However, these datasets provide only limited feedback on the underlying causes of architectural failures, typically restricted to metrics such as end-point error (EPE), occlusion statistics, and large-displacement ranges. This leads to imprecise claims regarding areas consecutive models have improved upon. In this paper, we present an analysis tool that enables the generation of customisable datasets, allowing controlled variation in displacement size, camera corruptions, luminance, and other factors. We demonstrate the utility of this tool by analysing the behaviour of different architectures under varying displacement sizes and in low-light settings.
